So after the mail upgrade, we were hoping this issue would have been resolved, however, it still persists.

Scenario: We have a domain admin who is administering 50+ domains. Whenever he attempts to edit or add anything, he is returned with that error while also displaying, Ex. 8 more aliases are available to be created. Others have less than him and are unaffected by that error.It also does not have any effect on Global Admins.
